Optimising a Probabilistic Model of the Development of Play in Soccer

We present a probabilistic model based on the one developed by Hernández Mendo and Anguera (Revista de Psicologíca Social, 16(1), 71–93, 2001). Here we have tried to break down the interaction contexts that the opposing teams are able to generate and transform during the game. We are aware that a given player or team does not produce consistent behaviour in similar situations. However, a degree of uncertainty is assumed to exist regarding whether the results obtained are a specific function of the analysis used. In order to carry out this research a category system which optimized that used in the previous model was developed. This system should enable the interaction between teams to be observed within the actual play of a soccer game. A lag sequential analysis was performed on the basis of a coding of the behavioural flow. After describing the behavioural patterns obtained a probabilistic model of the development of play in soccer is proposed.     

论科技权力与政治权力互动关系

大科学时代,科技权力与政治权力日益成为对人类社会发展影响深刻和显著的两大权力系统。一方面,科技权力不仅作为生产力的手段推动着经济社会的发展,还推动着政治权力的变革和完善。另一方面,政治权力通过行政的、法律的等手段不同程度地影响和制约着科技权力的发展速度,规定和引导着科技权力的发展方向。认清科技权力和政治权力的二元互动关系,无论对于我国科技权力的发展还是政治权力的进步都具有一定的意义。     

基于“服务交互”视角“中国服务”的餐饮特色培育研究

培育中国特色的餐饮服务对于本土餐饮品牌的经营与发展意义重大。本文在"中国服务"的内涵基础上,阐明"中国服务"的餐饮特色的内涵与特征;明确使"中国服务"成为走向世界的、独具中国特色的服务品牌,是培育"中国服务"的餐饮特色的核心目标,也是餐饮业发展的长远之计;基于"服务交互"的视角,为培育"中国服务"的餐饮特色,打造中国特色餐饮品牌的管理实践提供方法指导。旨在为餐饮业服务品质的提升,尤其是为本土中高端餐饮品牌的健康发展提供有益的参考。     

以城乡互动推进就地就近城镇化发展分析

“伪城镇化”、“半城镇化”现象的背后是中国城乡二元经济“一元化”过程中的“农民进城”与城市吸融功能不足的矛盾、“小城镇化浪潮”与农村城镇化的发展潜力不足的矛盾。结合中国国情的高质量城镇化发展模式在于守地式的就近就地城镇化发展,而守地式发展的关键在于农村产业发展,农村产业的发展又依赖于城乡市场与产业的互动。这需要发展立足农村的“产供销一体化”大型商贸企业,破解农村市场劳动力流转、土地流转、融资与技术及管理水平低下问题,构建城乡产业互动的交换利益基础,优化城乡产业体系配套和互补的对接方式,提升城乡产业合作的分工层次。     

我国生产性服务业与制造业互动需求结构及发展态势

本研究采用投入产出法与比较分析方法,对典型国家(或地区)的生产性服务业与制造业的互动需求结构进行分析。研究发现,经济发展水平、服务业发展水平、生产性服务业性质、制造业性质四方面是影响生产性服务业与制造业需求结构的重要因素。本文从四要素发展特点总结了生产性服务业与制造业需求的国际发展态势,即随着经济发展水平与服务业发展水平的提高,生产性服务业由对制造业需求显著转为对自身需求显著,而生产性服务业内部由以非知识密集型服务业为主导逐步转向以知识密集型服务业为主导。结合我国现状,本文最后提出了推动我国两类产业互动发展的若干政策建议。     

Controlling the commercialisation of science across inter-organisational borders: Four cases from two major Swedish universities

The purpose of this paper is to analyse how different types of controls are applied in different mechanisms for commercialising science, depending on the inter-organisational interactions involved. To achieve this purpose, we followed a multiple-case study design and selected four cases from Uppsala University and the Karolinska Institutet that provided variation in the commercialisation mechanisms (PET Centre, Ångström Materials Academy, Actar, and Karolinska Development). We find that action and result controls dominate in linear ‘spin-out’ funnel mechanisms, while interactive mechanisms entail a combination of action, result and personal controls. However, the inter-organisational interactions also impact which controls are applied in a commercialisation mechanism: conflicting goals between a few closely related organisations or limited external interactions are associated with result controls, while action controls dominate in the absence of external interactions if time and efficiency are key goals. Result controls also assume very different roles, depending on the inter-organisational context of a specific commercialisation mechanism.     

商业模式与企业战略的关系与相互作用

商业模式是企业战略制定的结果、实施的依据,两者会共享某些要素。企业战略的本质特点是时序的、纵向的行动和过程,而商业模式的本质特点则是空间的、横向的方式和状态,两者之间具有交融关系。不同竞争优势来源之间具有互补性和关联性,它们与商业模式在关键要素构成和价值创造方面具有一致性。商业模式对竞争优势来源等企业战略具有系统整合作用,而企业战略和创新理论对商业模式具有理论支撑作用。     

员工绿色行为对工作幸福感的影响研究

从员工个体视角,依据资源保存理论、自我决定理论探讨员工绿色行为、自我效能感与工作幸福感的关系。通过对收集到的196份数据进行相关分析和回归分析等来验证假设。实证分析结果表明,员工绿色行为和工作幸福感之间存在正向影响关系;自我效能感在员工绿色行为和工作幸福感之间起中介作用;以及互动公平在机制中的调节作用。研究结果丰富了员工绿色行为的后效变量研究,拓宽了员工绿色行为影响员工工作幸福感的机制研究,也为企业实践提供了有益的启示。     

Role of gender differences on individuals’ responses to electronic word-of-mouth in social interactions

Considering the significant effects of electronic Word-of-Mouth (eWOM), this research explores how individuals respond to eWOM and whether gender differences exist in their perceptions. To do so, by employing the perspective of social interactions, we examine the proposed relationships are different between genders. We collected data using a survey and tested the hypotheses via path analysis. The results indicate that, gender differences were found specific to search effort, product involvement, and information credibility. Women with strong online ties had a tendency to be more involved in the product information and to find the information more credible. In addition, when women had an increased search effort, they were more likely to have intention spread eWOM. This research provides insights to further research related to gender differences in eWOM by discussing implications for research and practice.     

投资者互动平台服务效能的诊断与优化研究
